IMPR OVEMENT IN INVALID BEDSTEAD S.

Specification forming part of Letters Patent No. 115,371, dated May 30, 1871.

I, GEORGE SMITH, of the town of Strat ford,in the county of Perth, in the Province of Ontario and Dominion of Canada, surgeon,

have invented certain Improvements in Beds, of which the following is a specification:

Nature and Objects of the Invention.

Description of the Accompanying Dmwt'nm Figure I, side elevation. Fig. II, transverse y section. Fig. III, plan showing portion of top, with canvas and head-rest. v

General Description. The main portion of the bedstead may b constructed, like any ordinary iron, brass, or

even wooden one, with the legs such a shape that they will accommodate the attachment of my improvements.

I have chosen an iron bedstead to illustrate my invention. In it the legs A are hollow, and belong to the lower or bedstead proper.

D and E are fitted into journals properly attached to the bedstead, and have cog-wheels F keyed to them, which gear into the racks .G, one into each leg or support 13, as shown in Fig. 11. I also place upon the shafts D and E two pulleys, H, around which passes the cord, chain, or belt I, connecting the two shafts D and E. r The handle J will fit any end of the two shaftsD and E; consequently, the whole being connected, as described, by placing the handle J on any end of the two shafts D and and Ev and turning it (the handle J) in the proper direction, the frame a can be raised or lowered, in order that the bedding may be changed or other necessary oifices performed. K is the head or pillow-rest, made of netting upon a light frame hinged at L, the supports M on either side of the bedstead holding the said rest at any angle desired.

Claim.

The combination of the legs A, made hollow to receive the supports'or legs B, which have racks out upon them, cog-wheels F which gear into, the racks on the said legs B, the two shafts D and E upon which are the two pulleys H, around which passes the cord, chain, or belt I, connecting the aforesaid combination in such a manner that upon placing the handle J on any end of the shafts D or E and turning the said handle in theproper direction the frame 0 can be raised or lowered at will, and the head or pillow-rest K, connected to and forming part of the aforesaid combination, as described.
